Abstract

In this paper the problem of coupling of acoustic sources in a confined space in treated. By considering the coupling of sources in a rectangular enclosure the set of coupled equations governing the acoustical behavior of enclosure are solved. The resulted model can be used to analyze the behavior of a multi-input multi-output (MIMO) active noise control (ANC) system in real application where coupling of sources can not be neglected. The developed model is an improved description of the acoustic environment inside the rectangular enclosure, especially in an ANC system when interaction among sources will change the radiation impedance of other sources.
